I'd like to run wolfram code (probably a .wls script) on a file or set of files by selecting them in the finder and using Right-click > Services.

For example, long ago I made a convenient service with Automator and Python to convert any selected images to jpeg:

An answer here would make for a very useful tutorial!


Update 1 (Response to @xslittlegrass's solution)

I got your solution to run directly in the terminal and also with the play button in the Automator app. But after I saved the workflow in ~/Library/Services/ and tried to use it from right click menu > service > workflow nothing seems to happen... Any ideas?

Here is one way to achieve that using the wolframscript and Automator:

  1. Create a automator script with two steps: a) "Get Selected Finder items" and b) "Run Shell Script"

enter image description here

  1. Define the Wolfram code in the file.wls. Here I'm using a simple example of combining two image files.

    #!/usr/bin/env /usr/local/bin/wolframscript files = DeleteDuplicates[$ScriptCommandLine[[2;;-1]]]; dir = FileNameTake[First@files, {1, -2}]; Export[FileNameJoin[{dir,"combined.png"}],ImageCollage[Import/@files]];

  2. Run the code through finder

  • $\begingroup$ @M.R. Did you have the "Get Selected Finder items" step in the automator script? For me, it appears in the right click menu, not the sub-menu of Service. $\endgroup$ Jul 27 at 22:28
